AO3404A
UMW · MOSFETs · SOT-23
AO3404A from UMW, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | G | input | GATE terminal of the N-channel MOSFET; the datasheet rates the gate-source voltage VGS at ±20 V. |
| 2 | S | passive | SOURCE terminal of the N-channel MOSFET; the datasheet gives no source-specific limit, and the 30 V VDS and 20 V VGS ratings apply to the device as a whole. |
| 3 | D | passive | DRAIN terminal of the N-channel MOSFET; the device is rated for VDS = 30 V and continuous drain current ID = 5.8 A at TA = 25°C. |
